I'm starting with my school project, that includes using router with OpenWRT as "sniffer", probably with tcpdump or Kismet. I have to choose the right device for this task. So if I'm not wrong, I need a router that supports monitor mode and promiscuous mode. I know that some WLAN chips supports this modes and some not.
I found few devices that should support OpenWRT and also supports other features that i need, but I'm not sure if they support these two modes. Is there any list of routers or WLAN chips that's support these modes under OpenWRT?
Considered devices:
Turris Omnia
Linksys WRT3200ACM
Netgear Nighthwak X45 R8700
Thank you for your advices.
BTW.: I'm new to OpenWRT.
Qualcomm Atheros wireless chips generally support monitor mode. For example:

Wiphy phy2

I haven't worked with any MTK, Marvell devices, nor any Broadcom devices in recent history. Broadcom wireless has very weak open-source support, in most cases.
